Thanks. I think most of those were due for our next release, anyway. But 
we'll
get it in, one way or another.

Not quite. The exported symbols belong to a public API for driver 
programmers.
We know about several users of this API, and there will be more, but I 
don't think
any of them are aspiring to have their code be included in the kernel.
